'They Were Afraid' in the Bible

And he said to them, Where is your faith? And they were afraid, and wondered, saying one to another, Who then is this, that he commandeth even the winds and the water, and they obey him?

And they went out to see what had been done. And they came to Jesus and found the man from whom the demons had gone out sitting, clothed, and in his right mind, at the feet of Jesus; and they were afraid.

But as he was saying this, there came a cloud and overshadowed them; and they were afraid as they entered the cloud.

But they knew not the meaning of these words, and it was hidden from them, that they might not perceive it; and they were afraid to ask him about these words.
